Abstract (en)

[origin: FR2764282A1] The invention concerns a compound based on titanium, cerium and alkaline or earth-alkaline, its preparation methods and use as colouring pigment, characterised in that it corresponds to formula (1) MxCeyTizOt in which M represents an alkaline or earth-alkaline and x, y and z verify the following equations: 0.1 </= y/z </= 1.5; 1 </= (x+z)/y </= 15; x+y+z = 1; (x+3y+4z)/2 </= t </= (x+4y+4z)/2. The product can be prepared by forming a mixture comprising a salt, sol or suspension of titanium, a compound of element M and a cerium compound then drying and calcining the resulting mixture. In a second embodiment the mixture is prepared by bringing together a cerium compound and a titanium compound in a liquid medium; adding a base to the resulting mixture, thereby obtaining a precipitate; bringing together a compound of element M and the resulting precipitate; drying and calcining the resulting mixture.
